IMPROVEMENT IN TILE-MACHINES.

Specification forming part of Lettcrs Patent No. l52,890, dated July 7,1674; application filed January 12, 1874.

To all whom it may concern Be it known that I, J ULrUs WHITEHEAD, ofDarwen, in the county of La-ncaster and Kingdom ofEn gl and,re-cl'ay-works mana-ger,

\ have invented certain improvements in machinery or apparatus to beemployed in the molding of sanitary tubes or pipes, of which thefollowing is a specification:

This invention relates to improvements in the dies or apparatus forforming or molding the sockets of sanitary tubes or pipes, and in theapparatus for operating such machinery, whereby the frequent damage tothe sockets of the tubes or pipes during the process of molding isobvia-ted.

lVhen making a number of pipes at one operation, I affix the dies,constructed as herein after described, to the bottom of theclaycylinder. hen making pipes of large diameter, one at a time, Iconstruct the clay-cylinder with its lower end shaped according to theform of socket required. At each side of the said cylinder is aguide-rod. Extending' from rod to rod, and immediately under theclaycylinder, is a table or bed rail on which the soeket-blocks rest.rlhe table or bed rail ascends the guide-rods by means of chains orcords and counterbalanceweights passed over pulleys. The socket-blocksare thus brought into proper position within the socketed end of theclay-cylinder, and there held by catches until the piston descends,partially forcing the clay into the socket-dies. 4The steam is now shutoft' and the catches are released. rI he steam being again turned on,the piston resumes its downward stroke, forcing down the table orcross-rail to its original position, and completing the formation of thecylindrical part of the tube or pipe. The completed tubes or pipes arenow removed from the table or bed rail, (the boards 011 which thesocketblocks rest are hinged so as to facilitate re moval of the pipesby tilting them onto a bearing-board hereinafter described,) and thesocket-blocks withdrawn from the sockets of the pipes and replaced ont-he table or bedrail ready to repeat the operation.

The die of each socket is perforated and its interior lined with cloth,through which air is admitted on the farther descent of the piston, soas to prevent formation of vacuum.

The following is a full and complete specication of this invention,reference being had tothe live sheets of drawings accompanying the same.

Figure l is afront elevation ofa machine for molding nine sanitary pipesor tubes at one operation, and constructed according to this myinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a section,showing interior of the dies, drawn to an enlarged scale. Fig. el is aplan view of the table or cross-rail and the socket-blocks, and it willbe seen that the dies are constructed of complete rings, and not inhalves or part rings, as heretofore. Fig. 5 is a detached die andsocket, enlarged scale. Figs. 6 and 7 are elevation and plan of abearer. f

A is the clay-cylinder, which is of the ordinary character, the claytherein being forced or expelled therethrough and into the dies thereofby a piston and piston rod or rods, as usual. B are the socket-molds,which are secured to the lower part of the Claycylinder. The beveledpart B1 forms the shoulder of the socket. rIhis part, by preference, Imake of wood, and it is secured between the parts B2 and B3 by the boltsB4. F F are holes formed in the part B1. (See Figs. 3 and 5.) From theholes F F branch or radiate other smaller holes F F. The object of theseperforations is to admit atmospheric air to the socket-dies when a pipeor pipes are being forced from the cylinder and molds, and so preventdamage to the pipes or tubes by the formation of a vacuum or vaeuitybetween the socket-shout der of the pipe or tube and the interior of thedie. The perforated face of the part B3 is faced or covered with cloth,linen, or other fabric, lV, to prevent the clay being forced into andstoppin g up the holes F', and so preclndin g the admittance of thenecessary snpply of air. On each side of the clay-cylinder A is aguide-rod, H, and extending from rod to rod is a table or' bed-rail, J,on which the ordinary socket-block K rests. The table or bed-rail Jascends the guide-rods by means of the counterbalance-weights andpulleys K2 K2. The socket-blocks K' are thus brought into properposition within the socket-formin g end of the clay-cylinder, (see Fi g.2,) and there held by the catches L catching and holding thc flanges ofthe nuts M. rlhe nuts M may readily be adjusted to any height on theguiderods H by lneans Ot' the chasing or screwing` thereon. Theclay-piston. now partially descends within the clay-cylinder, forcing`the cla-y into the socket-dies, and so forming` the socketed end of thepipes or tubes. The catches L are now released from the angcs of thenuts M by hand or foot lever connected at their junction N, and theclay-piston resumes its downward stroke, forcing` down the table orbed-rail J, and forming the cylindriA cal part l of the tube Or pipe.

Any convenient number ot' such dies may be employed, according1 to thepower of the clay-piston and capacity of theclay-cylinder, the cores Rlbeing suspended by the bridges t2, as will be clearly understood.

The perforated portions otl the dies are arranged between the plates B2and B3, and the whole secured to the bell or bottom ot' theclay-cylinder by bolts. rlhe bed'rail J will of course be provided witha corresponding number ot' socket-blocks, K, as shown at Fig. 4. Theboards T, On which the socketblocks rest, are hinged, in Order tofacilitate removal by tilt-ing the pipes S when molded Onto the bearerS, on which they are carried or removed to the drying-room. Thesocket-blocks K will be greased or oiled as usual.

Having1 thus fully described the nature and particulars of this lny saidinvention, together with the manner in which the saine is to be or maybe performed or carried into practical operation, I 'would have itdistinctly understood that I claim as my inventionl. The catches L andadjustable nuts M onl the guide-rods, as and for the purpose hereinfully described and shown.

2. rlhe combination, with a clay-cylinder, A, of dies or molds B,constructed Of complete annular portions B1 B2 B3, the part Bl being'beveled to form the shoulder of a pipe Or tube, having holes or passagesF F radiating,` therefrom, and a surface of linen or other retieulatefabric, WT, all constructed and operating substantially as and for thepurpose specilicd.
